Spur gear. Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. Viewing the gear at 90 degrees from the shaft length (side on) the tooth faces are straight and aligned parallel to the axis of rotation. Looking down the length of the shaft, a tooth's cross section is ...
The module is the measure of gear tooth size which is normally used for metric system gears. It is similar to the Diametral Pitch (DP), which is commonly used for UK system (inch measure) gears but they differ in the units used and in that they bear a reciprocal relationship. Module is the pitch circle diameter divided by the number of teeth.
The involute gear profile, sometimes credited to Leonhard Euler, [1] was a fundamental advance in machine design, since unlike with other gear systems, the tooth profile of an involute gear depends only on the number of teeth on the gear, pressure angle, and pitch. That is, a gear's profile does not depend on the gear it mates with.
A line drawing of a spur gear with an involute profile. This was drawn in Solid Edge and Inkscape using Unwin's Construction. The pitch diameter is 12mm and there are 18 teeth, giving a module of 2/3. Date: 25 August 2007: Source: Self-made
Gear manufacturing refers to the making of gears. Gears can be manufactured by a variety of processes, including casting , forging , extrusion , powder metallurgy , and blanking . As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear.
The rigid design of the gears and houses allow for very high pressures and the ability to pump highly viscous fluids. Many variations exist, including helical and herringbone gear sets (instead of spur gears), lobe shaped rotors similar to Roots blowers (commonly used as superchargers), and
